Soil Preference and Burrow Characteristics of Two Theraphosidae Species in Penang Island, Malaysia

  Soil Preference and Burrow Characteristics of Two Theraphosidae Species in Penang Island, Malaysia Abstract Tarantulas play a crucial role in maintaining ecological balance by regulating insect populations. However, little is known about the soil preferences and burrow structures of tarantulas in Malaysia. This study aims to determine the soil preference as well as the burrow structure of  Coremiocnemis cunciularia  and  Chilobrachys andersoni  from Penang Island. The soil characteristics of the soil samples collected around the burrows of  Coremiocnemis cunciularia  (n = 30) and  Chilobrachys andersoni  (n = 30) were determined using soil texture analysis. The measurements and burrow structures from adults and juveniles of  Coremiocnemis cunciularia  and  Chilobrachys andersoni  were determined. It was revealed that the moisture content and clay percentage in the soil samples around burrows of  Chilobrachys anderso...

Grand challenges in arachnid genetics and biomaterials

Arachnids, particularly spiders, flourish in abundance within most ecosystems (Blamires et al., 2007; Oxbrough and Ziesche, 2013; Henneken et al., 2022; Agnarsson, 2023; Fonseca-Ferreira et al., 2023). Arachnids such as spiders, scorpions and mites create and/or secrete a range of biomaterials, including silks, glues, adhesives, nano-fibres, venoms and other toxins, and chitin associated molecules used to form sensory systems, armour, body colouration/luminescence, and locomotion (Kuntner, 2022). Studies focusing on the evolutionary and ecological aspects of these kinds of arachnid secretory products have established that extended phenotypic features enable arachnids their immense niche flexibility (Agnarsson et al., 2010; Blamires et al., 2012a; Blamires and Tso, 2013; Blamires et al., 2017a; Blamires et al., 2017b; Lacava et al., 2018; Viera et al., 2019; Henneken et al., 2022; Kuntner, 2022). Nonetheless, the genetic features and the expression patterns implicit in facilitating this flexibility remain largely unexplored.
